Hyperuniform disordered phononic structures
George Gkantzounis, Timothy Amoah, Marian Florescu
We demonstrate the existence of large phononic band gaps in designed hyperuniform (isotropic) disordered two-dimensional (2D) phononic structures of Pb cylinders in epoxy matrix. T…
High-Q Optical Cavities in Hyperuniform Disordered Materials
Timothy Amoah, Marian Florescu
We introduce the first designs for high-Q photonic cavities in slab architectures in hyperuniform disordered solids displaying isotropic band gaps. Despite their disordered charact…
Isotropic Band Gaps and Freeform Waveguides Observed in Hyperuniform Disordered Photonic Solids
Weining Man, Marian Florescu, Eric Paul Williamson +7
Recently, disordered photonic media and random textured surfaces have attracted increasing attention as strong light diffusers with broadband and wide-angle properties. We report t…
Optical cavities and waveguides in hyperuniform disordered photonic solids
Marian Florescu, Salvatore Torquato, Paul Steinhardt
Using finite difference time domain and band structure computer simulations, we show that it is possible to construct optical cavities and waveguide architectures in hyperuniform d…
Effects of Random Link Removal on the Photonic Band Gaps of Honeycomb Networks
Marian Florescu, Salvatore Torquato, Paul J. Steinhardt
We explore the effects of random link removal on the photonic band gaps of honeycomb networks. Missing or incomplete links are expected to be common in practical realizations of th…
Complete Band Gaps in 2D Photonic Quasicrystals
Marian Florescu, Salvatore Torquato, Paul J. Steinhardt
We introduce a novel optimization method to design the first examples of photonic quasicrystals with substantial, complete photonic band gaps (PBGs): that is, a range of frequencie…
Designer disordered materials with large complete photonic band gaps
Marian Florescu, Salvatore Torquato, Paul J. Steinhardt
We present designs of 2D isotropic, disordered photonic materials of arbitrary size with complete band gaps blocking all directions and polarizations. The designs with the largest…
Single photons on demand from 3D photonic band-gap structures
Marian Florescu, Stefan Scheel, Hartmut Haeffner +4
We describe a practical implementation of a (semi-deterministic) photon gun based on stimulated Raman adiabatic passage pumping and the strong enhancement of the photonic density o…
